ClouD ForesT..

A cloud forest, also called a fog forest, is a generally tropical or subtropical evergreen montane moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the saddles of mountains, where moisture introduced by settling clouds is more effectively retaine.Only 1% of the global woodland is covered by cloud forests.

Importance of cloud forests

• Watershed function. Because of the cloud stripping strategy the effective rainfall can be doubled in dry seasons and increase the wet season rainfall by about 10 percent.

• Vegetation. Tropical montane cloud forests are not as species-rich as tropical lowland forests but they provide the habitats for many species that are found nowhere else.

• Fauna. The endemism in animals is also very high. One of the best known cloud forest mammal is the Mountain Gorilla (Gorilla b. beringei).

Current situation

In 1970, the original extent of cloud forests was around 50 million hectares. Population growth, poverty and uncontrolled land use have contributed to the loss of cloud forests. The 1990 Global Forest Survey found that 1.1% of tropical mountain and highland forests were lost each year, which was higher than in any other tropical forests.In Colombia, one of the countries with the largest area of cloud forests, only 10-20% of the initial cloud forest cover remains.Significant areas have been converted to plantations, or for use in agriculture and pasture. Important crops in montane forest zones are tea and coffee, but also logging special species such as Podocarpus causes changes to forest structure.Currently, one third of all cloud forests are protected.
